Execution Reports - New

Pending New and New execution report message formats and fields.

Execution Reports – New

After submitting a New Order, Paxos sends two Execution Reports confirming receipt and acceptance:

• Pending New (ExecType (150) = A) — Acknowledgement that the order was received.
• New (ExecType (150) = 0) — Confirmation that the order is active on the book.
